- 6. Adding Fractions with Unlike Denominators *The first step to add fractions with different denominators, is to find the least common denominator (LCD). An easy way to do this, is to list the multiples of each denominator. Lets find the multiples of 2 and 3. To do this, simply multiply the number 2 by 1,2,3,4 and so on, until a common number is identified. In the below example, the common number between 2 and 3 is 6. 2: 2, 4, 6, 8, 10 3: 3, 6, 9, 12, 15 Equation
